// 1.定义路由
// routes是一个对象数组，里面包含了path、name、component对象
const routes = [
  {
    path: '/', redirect: '/login'
  },
  {
    path: '/login', component: Login
  },
  {
    path: '/home', component: Home, redirect: '/welcome', children: [{ path: '/welcome', component: Welcome }, { path: '/users', component: Users }, { path: '/rights', component: Rights }, { path: '/roles', component: Roles }, { path: '/categories', component: Cate }, { path: '/Params', component: Params }, { path: '/goods', component: List }, { path: '/goods/add', component: Add }, { path: '/orders', component: Order }, { path: '/reports', component: Report }]
  }
]

// 2.挂载路由
const router = new VueRouter({
  routes
})

// 3.挂载路由导航守卫，即每次路由跳转的时候都要进行判断，是否有 token
router.beforeEach((to, from, next) => {
  if (to.path === '/login') return next()
  const tokenStr = window.sessionStorage.getItem('token')
  if (!tokenStr) return next('/login')
  next()
})

// 4.导出默认路由
export default router
